Split shot cutter is used to sever any collar or connection downhole where larger-size, radial-cutting tools requiring a more complicated running process, slower running time or special maneuvering because of the flared cut. The split shot cutter uses magnets to adhere to the pipe wall and creates a clean, longitudinal slit through the collar or connection. After detonation, the split collar or connection allows the pipe to be freed for easy removal.

A split sleeve wire marker has a lap type joint. It provides minor diameter changes such that the marker grips tightly around the wire. The split sleeve markers at temperatures above 150 degrees F the split joints are welded with cement.

Split system heat pumps use small-diameter piping that feeds refrigerant into a fan-coil unit mounted high up on a wall in each room. A fan in the unit blows air over the coil and delivers cooled air to the room. Systems differ in the way they heat. Some use the reverse cycle of the heat pump; others contain a hot-water coil connected to a boiler or water heater. A third means is a simple electric resistance coil.
